APPROXIMATION OF AND BY COMPLETELY MONOTONE FUNCTIONS

  • R. J. LOY (a1) and R. S. ANDERSSEN (a2)

Abstract

We investigate convergence in the cone of completely monotone functions. Particular attention is paid to the approximation of and by exponentials and stretched exponentials. The need for such an analysis is a consequence of the fact that although stretched exponentials can be approximated by sums of exponentials, exponentials cannot in general be approximated by sums of stretched exponentials.
